3.4 Switch Setting Adjustment
Access to switches is achieved by removing control unit from base, unclipping plastic panel from rear of control unit
and sliding PCB from housing. After setting switches, reassemble by reversing the disassembly procedure.
Figure 3 :
There is one set of four switches on the pcb of the MES*L unit, which is labelled SW1. This has four colour coded switches
which can be off to the left (in the diagram above) towards the word OFF on the switch itself, or ON to the right, in the direction
of the arrow towards the numbers 1, 2, 3 and 4.
